The invention relates to a method for the production of polyether alcohols by catalytic addition of at least two alkylene oxides to H-functional starting materials. Said method is characterised in that at least one multi-metal cyanide compound is used as catalyst and in the course of the addition to the starting material at least one oxyalykylene unit is incorporated, during which a common dosing of at least two alkylene oxides occurs, whereby during said common dosing the ratio of the amounts of alkylene oxides to each other is varied.

L'invention concerne un procédé de production de polyéther-alcools par addition catalytique d'au moins deux alkylènoxydes à des substances de départ à fonction H, ce procédé se caractérisant par le fait que l'on utilise comme catalyseur au moins un composé cyanuré polymétallique et que, pendant l'addition des alkylènoxydes à la substance de départ, est introduit un bloc oxyalkylène dans lequel un dosage commun d'au moins deux alkylènoxydes est effectué, dosage commun pendant lequel le rapport quantitatif entre les alkylènoxydes dans le mélange est modifié.
